1 claim. 1

This invention relates to improvements in tobacco presses.

An object of the invention is to provide an improved tobacco press which will include a xed clamping plate or base member which will be supported on transverse rails, and will cooperate with a clamping plate resiliently supported at one end of said base member and a cam actuating member for engaging the opposite end of the clamping plate to force the same towards the base member to press tobacco leaves therebetween.

Another object of the invention is to provide an improved tobacco leaf press which will include a fixed clamping plate and a hinged resiliently tensioned clamping plate, together with means l for varying the degree of clamping action and a cam actuating member for operating the hinged clamping plate.

A further object of the invention is to provide an improved tobacco leaf press which will include cooperating clamping plates hinged at one end, and adjustable fulcruming means for varying the clamping action on said plates, and a pivoted cam press operating lever for forcing the plates toward each other.

Another object of the invention is to provide an improved tobacco leaf press which will be highly efficient in operation and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application:

Figure 1 is a plan View of the improved tobacco leaf press;

Figure 2 is a longitudinal sectional view taken on the line 2-2 of Figure 1;

Figure 3 is a sectional View of the press base with the top press plate and cam actuator removed, as taken along line 3 3 in Figure 2;

Figure 4 is a detail side elevation of the spring hinge pin and adjustably positioned bearing stick;

Figure 5 is a perspective view of one end of the bearing stick; and

Figure 6 is a detail view of the hinge bolt.

Like characters of reference are used throughout the following specication and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided a base press plate I substantially rectangular in shape and supported upon the transverse rails 2 and 3 disposed at the opposite ends of the plate I.

The spaced eye bolts 4 and 5 are placed through one end of the plate I and through the rail 2 and pivotally supporting the upwardly extending hinge or bearing bolts l, having an arcuate free end portion 8 defining an eye 6, which bolts 7 support the washers IE] and coil tensioning springs I and adjustable wing nuts II which may be screwed down to vary the tension on the clamping press plate 3. A transversely extending bearing strip I 2 is secured to the upper surface of the opposite end of the clamping press plate 9 and is covered on its top and end surfaces by the metal Wear strip I3. Reinforcing strips I4 and I5 are secured in spaced relation longitudinally of the top of said press plate 9 by means of said bolts l extending therethrough at one end, and the bolts i6 extending through their opposite ends.

An upstanding bracket I'I having spaced ears is secured to the base clamp plate I by means of the bolts i8 and pivotally supports the cam clamp member I on the pin 20 connected between said bracket ears.

The cam surface of the cam clamp member I9 rides on the metal bearing strip I3, and a handle 20|) is formed on its end.

A pair of metal guide plates 2I and 22 are secured to the opposite sides of the base clamp plate l and extend upwardly therefrom, and are formed with the spaced bearing slots 23 and M in which the fulcrum stick 25 is adapted to be selectively positioned transversely of the upper surface of the base press plate I to vary the clamping action on the tobacco leaf when placed in the press and the cam clamp is operated. The fulcrum 25 is provided to determine the amount of clamping action that will be applied on the tobacco to be dried, since the position of the fulcrum determines the size of the space between it and the clamping plate e. As the spring Ilil urges the press plate 9 into engagement with 'the free end 8 of the eye bolt 1, the precise position of the fulcrum determines the distance between it and the press plate, thus determining the pressure which may be applied on the tobacco. It is to be understood that while the free end 8 of the bolt i prevents the plate from contacting the fulcrum 25 when the tobacco is not in the tobacco tions of the leaf are pressed. Further pressure on the leaf is then obtained by positioning the leaf with its axis parallel to the fulcrum 25 so that pressure can be applied between the clamping plate and base plate as Well as between the clamping plate and the fulcrum 25.

From the foregoing description it will be apparent that there has vbeen provided a highly efcient form of tobacco leaf press. The device is opened by releasing cam i9 from engagement With plate 9, tobacco to be dried is placed within the space dened by base plate I and plate 9, after which cam I9 is rotated by handle 258 to engage the free end of plate `9 on wear plate I3 for pressing of the tobacco.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from-the spiritfof the invention.

Having thus described the invention what is claimed as new and desired to secure by Letters Patent of the United States is:

A tobacco leaf comprising a base press i; ng ress plate, hinge means securing said clai ping plate te said base plate, a pivoted clamping member secured to said vbase piate and engaging said clamping plate for pressn ing action, a vertically extending guide plate 'ree end of said eye bolt, said eye bolt being atn 'tached to said base plate.

4 secured at the side of said base plate, said guidel plate having spaced notches therein, and a fulcrum stick selectively retained in one of said notches for varying the clamping action of said press, said hinge means comprising an eye bolt, said eye bolt having a free end and an end extending through said clamping plate, said free end of said eye'bolt constituting'a stop for said clamping p ate and tension means on said eye bolt urging said clamping plate into engagement with the JEWELL MYALL HURST, Eare'zttvfznt of' the lEstate of George W.
